Various systems and methods are provided for electrically controlled flush applications. In one embodiment, an apparatus includes an activation assembly configured to initiate a flush of a flush assembly based upon a position of the activation assembly. The activation assembly includes a position sensor that senses a transition from a neutral position to a first position and a restraint mechanism that prevents a return to the neutral position for a predefined period of time corresponding to the flush duration. In another embodiment, a flush activation assembly includes an activation control box with a position sensor that provides an indication that a cable anchor has transitioned from a neutral position to a first position to initiate a flush of the flush assembly and a restraint mechanism that prevents the cable anchor from returning to the neutral position in response to the indication from the position sensor.

An optical system includes one or several passive optical detectors sensitive to ambient (room) light for controlling, for example, the operation of automatic faucets or automatic bathroom flushers. The passive optical sensors provide signals to flow controllers, including control electronics and flow valves and require only very small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. To control the operation of automatic faucets or automatic bathroom flushers based on ambient light, the controller executes novel algorithms.

A remote control device for remotely controlling a toilet device is provided. The remote control device includes a casing, a power generation device, buttons, and a link mechanism. The casing forms a contour of the remote control device. The power generation device is housed in the casing and is capable of generating a power by being pressed. The buttons is provided on a surface of the casing and each is configured to activate a function of the toilet device. The link mechanism is configured to move so as to press the power generation device when one of the buttons is pressed. The buttons is supported on the casing by an elastic member so that, when one of the buttons is pressed to cause motion of the link mechanism, one other of the buttons not pressed is not affected by the motion of the link mechanism.

According to one embodiment, a remote control device for a toilet device includes an operation button and a power generator. The operation button is capable of a push operation and is configured to operate an equipment in response to the push operation. The power generator is configured to generate a power by being pressed in response to the push operation. A direction of the pressing is parallel to a wall surface on which the remote control device is placed.

Exemplary embodiments of a pet toilet are provided. A pet toilet is provided having a base, a standing surface provided on the base configured to allow a pet to stand on the standing surface, a first flush mechanism to provide water for flushing the standing surface, a rim tube connected to the first flush mechanism configured to provide water from the first flush mechanism to the standing surface, and at least one water outlet disposed on the rim tube for providing water from the first flush mechanism to the standing surface. The flush mechanism can be an automatic flush mechanism triggered by one or more motion sensors. The standing surface can have a concave surface.

A tankless toilet includes a bowl, a trapway, and a jet. The bowl includes a rim at an upper portion of the bowl and a sump at a lower portion of the bowl. The trapway extends from the sump to a drain. The jet includes a main channel configured to receive a supply of water from a supply conduit, and a plurality of distribution channels configured to introduce water received from the main channel to at least one of the sump and the trapway. The jet is configured to receive the supply of water from the supply conduit at a first flow rate and induce a flow from the supply of water into the trapway at a second flow rate greater than the first flow rate to prime a siphon within the trapway. The second flow rate is greater than the first flow rate prior to priming the siphon.

A toilet comprising a rinsing seat, a rimless bowl, and a helical loop trapway is disclosed. An annular cavity for the purpose of storing and dispensing rinse water from the rinsing seat is disclosed. In one embodiment, the rinsing seat includes a pressurized line which can be pressurized by a compressible membrane compressed by a toilet user. Outlet nozzles arranged about the circumference of the rinsing seat and designed to dispense rinse water at the rimless bowl are disclosed. Rinsing seat supports, hinge assemblies, and seat sensors which offer additional functionality to the rinsing seat are also disclosed. A steep interior surface and hydrophobic material for the rimless bowl are also disclosed and claimed herein.
